This paper describes the prototype of a real-time responsive audio display for an ambient intelligent game named socio-ec(h)o. The audio display relies on a gradient response to represent and anticipate player action. We describe the audio display schema, and discuss results of our current experimentation in guiding player actions through types of audio feedback, for creating sound recognition, perceptions of change and sound intensity.
